We generate a License based on a unique number from your machine called a System Key. Since the License is based on the System Key, you may only run the software on the machine that it is licensed for.

To obtain your System Key:

1. Run Silhouette and select Help > Edit License to open the Licenses window.

2. Click the Copy button at the top right.

3. When requested, use Ctrl/Cmd-V to paste your System Key into the appropriate text field when purchasing.
